Community / Unofficial — This app is not affiliated with or endorsed by the TREK project. It is an independent, open-source mobile client for use with TREK.
Android app for TREK — connect to any self-hosted TREK instance from your phone.
A thin WebView wrapper that lets you use your self-hosted TREK trip planner as a native Android app. Enter your server URL on first launch and you're done.
- Any TREK instance — enter your server URL on first launch
- Full screen — no browser chrome, feels native
- Cookie persistence — stay logged in across app restarts
- Back button navigation — navigates page history, not app exit
- Offline handling — shows a retry page instead of crashing
- Settings — change server, clear cache
- Zero telemetry — WebView metrics explicitly opted out
- No third-party cookies — only your TREK server's cookies
- Android 8.0+ (API 26)
- A running TREK instance accessible from your phone over HTTPS
Note: Embara requires your TREK server to use HTTPS. Plain HTTP connections are not supported. If you're self-hosting on a local network, set up a reverse proxy with a TLS certificate (e.g., Caddy, nginx + Let's Encrypt, or a self-signed cert).
